study of the effect of a 5-day regimen of study drug on peripheral stem cell mobilization in healthy participants

Conditions: Healthy Participants

Summary: a multi-center, open-label, single-arm clinical study to assess effects of a 5-day regimen of 10 micrograms per kilogram (mcg/kg) of tbo-filgrastim administered subcutaneously daily on the mobilization of cluster of differentiation 34+ (cd34+) cells in at least 60 healthy male and female participants. the pharmacokinetics, pharmacodynamics, safety, tolerability, and immunogenicity of tbo-filgrastim will be assessed.

gastrointestinal, hematologic, respiratory, psychiatric, renal, hepatic, cardiac, metabolic (such as, fructose intolerance), neurological, or any other disease or condition which may influence the physiological metabolic turnover (such as, severe endocrine diseases, febrile condition, severe infections), which may interfere with the study objectives, or which could expose the participant to undue risk through the participation in the clinical study * the participant has had: (1) a trauma or surgery in the past 2 months; (2) a clinically relevant illness within 4 weeks before the first dose of tbo-filgrastim; (3) any acute illness within 1 week before the first dose of tbo-filgrastim; or (4) symptoms of any clinically relevant or acute illness at baseline * the participant has existence or recent history of persistent pulmonary infiltrates, recent pneumonia, recent bronchitis, recurrent lung infections, or history or evidence of any lung disease including asthma, or current

sonography at screening, defined by length of spleen more than 12.3 centimeters (cm) and clinical judgment * the participant has a history of malignancy, including hematologic malignancy, except for appropriately treated non-melanoma skin carcinoma in the last 5 years * the participant has a clinically significant deviation from normal in ecg recordings or physical examination findings, as determined by the investigator * the participant is pregnant or lactating, or was pregnant in the previous 6 months, or intends to get pregnant during the study or within 30 days after the last dose of study drug * the participant has habitually consumed, within the last 2 years, more than 21 units of alcohol per week, or has a history or evidence of alcohol, narcotic, or any other substance abuse as defined by the diagnostic and statistical manual of mental disorder, fifth edition (dsm-v, american psychiatric association 2013). note: a unit of alcohol is equal to 1 ounce (29.6

products, or substances: 1. any imp within 30 days or 5 half-lives (whichever is longer) before the first dose of tbo-filgrastim, or in the case of a new chemical entity, 3 months or 5 half-lives (whichever is longer) before the first dose of tbo-filgrastim 2. known history of treatment with blood-cell colony-stimulating factors 3. current or recent (within 4 weeks) treatment with lithium * the participant has donated plasma within 7 days before screening or has donated blood within 56 days before screening * the participant has a documented or self-reported history of tuberculosis or recent travel to countries of endemic disease (last 8 weeks) * the participant has 1 or more clinical laboratory test value(s) outside the range specified below, or any other clinically significant laboratory abnormality as determined by the investigator or medical monitor: 1. hemoglobin less than or equal to (\<=) 12.5 grams per deciliter (g/dl) (women) and hemoglobin \<=13.5 g/dl (men) 2. alanine aminotransferase (alt) or aspartate aminotransferase (ast) values of greater than (\>) 3 \* the upper limit of the normal range (uln) 3. total bilirubin of \>2 \* uln 4. findings of cholestasis (eg, abnormal values of alkaline phosphatase) * the participant has a positive test result for human immunodeficiency virus (hiv), hepatitis b surface antigen, antibodies to hepatitis c virus, immunoglobulin m (igm) antibodies to cytomegalovirus, human t-lymphotropic virus, west nile virus, malaria, or syphilis * the participant has a documented or self-reported history of tuberculosis or recent travel to countries of endemic disease (last 8 weeks) * the participant has, after resting for 5 minutes, increased blood pressure (bp) (defined as systolic bp in seated position of more than 145 millimeters of mercury \[mm hg\] or diastolic bp in seated position of more than 95 mm hg), or low bp (defined as systolic bp in seated position of less than 90 mm hg or diastolic bp in seated position of less than 45 mm hg) (only 2 rechecks of the participant's bp are permitted for eligibility purposes) * the participant has, after resting for 5 minutes, a pulse in seated position of less than 45 or more than 90 beats per minute (only 2 rechecks of the participant's pulse are permitted for eligibility purposes) * the participant is unwilling to refrain from
